Implement copy for data sets (SDK, CLI, VSCE)

[ATorrise]

What It Does

• Added copyDataset to SDK with fromDataset, toDataset, replace, overwrite options
• Added zowe zssh copy data-set CLI command
• Implemented copyDataSetMember in VSCE for Zowe Explorer integration

How to Test

CLI

Replace USERID with your chosen HLQ

Test 1: Copy to new target

# Setup
zowe zssh create data-set "USERID.COPY.SRC" --dsorg PO --dirblk 2
echo "test data" | zowe zssh write data-set "USERID.COPY.SRC(MEM1)"

# Copy to new target (TGT doesn't exist yet)
zowe zssh copy data-set "USERID.COPY.SRC" "USERID.COPY.TGT"

# Verify: TGT should have MEM1
zowe zssh list data-set-members "USERID.COPY.TGT"

Test 2: Copy without flags fails on existing target

# Add a member to TGT that doesn't exist in SRC
echo "target only" | zowe zssh write data-set "USERID.COPY.TGT(MEM2)"

# This should fail - target already has MEM1
zowe zssh copy data-set "USERID.COPY.SRC" "USERID.COPY.TGT"
# Expected: Error about target already existing

Test 3: --replace overwrites matching members, keeps others

# Update SRC member with new content
echo "updated source" | zowe zssh write data-set "USERID.COPY.SRC(MEM1)"

# Copy with replace
zowe zssh copy data-set "USERID.COPY.SRC" "USERID.COPY.TGT" --replace

# Verify: MEM1 has "updated source", MEM2 still exists
zowe zssh view data-set "USERID.COPY.TGT(MEM1)"
zowe zssh view data-set "USERID.COPY.TGT(MEM2)"
zowe zssh list data-set-members "USERID.COPY.TGT"
# Should show both MEM1 and MEM2

Test 4: --overwrite replaces target completely

# Copy with overwrite - this deletes all TGT members first
zowe zssh copy data-set "USERID.COPY.SRC" "USERID.COPY.TGT" --overwrite

# Verify: Only MEM1 exists (MEM2 deleted)
zowe zssh list data-set-members "USERID.COPY.TGT"

Cleanup

zowe zssh delete data-set "USERID.COPY.SRC"
zowe zssh delete data-set "USERID.COPY.TGT"

Test cases for reviewerss to verify

• CLI zowe zssh copy data-set works for PS data sets
• CLI zowe zssh copy data-set works for PDS data sets
• CLI zowe zssh copy data-set works for individual members
• CLI --replace flag works correctly
• CLI --overwrite flag works correctly
• VSCE copy/paste works in Zowe Explorer Data Sets view
• Error messages are clear when copy fails
